alIGnInG THe GIRTs
Installation of the building walls is generally done before the roof . Before starting the wall
installation, check to be sure that the eave strut and girts are straight and plumb . One method of
aligning the girts is to cut temporary wood blocking to the proper length and install between the
lines of girts . This blocking can be moved from bay to bay, which will reduce the number of pieces
required . Normally, one line of blocking per bay will be sufficient . Banding can also be used to hold
the girts straight and plumb .
Typical construction of the wood blocking is show below . A 2" x 4" minimum board size should be
used . Refer to the cross section framing drawing that accompanied the building to determine the
girt spacing .
